CHESTER W. CANINE, OF CINCINNATI, OIIIO.

INDICATING ME CHANISM.

To all whom it may concern.'

Be it known that I, CHnsTER W. CANINE, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in IndicatingMechanism, of which the following is a specification.

My invention relates to an indicating mechanism.

The object of the invention is to produce an attachment to he used inconnection with machines which will automatically actuate a signal atthe end of the operation, and continue to actuate the signal until theoperator stops the machine. Such a machine is useful in numerous classesof work, for instance, with washing machines, eXtractors, etc. In such amachine some fabrics require a treatment of, say, ten minutes, whileothers require a treatment of thirty minutes. The dial is set for theselected period of operation and the machine started; at the end of theset time the signal sounds and notifies the operator or the foreman thatthe work is com leted.

T e mechanism of my attachment is in driven connection with themechanism of the machine, so that the signal is mechanically accurate.

The features of my invention will be more fully set forth in thedescription of the accompanying drawings, forming a part of thisspecication, in which:-

Figure 1 is an end elevation of my device. Fig. 2 is a front elevationof my device. Fig. 8 is an end elevation of the same from the oppositeside to that of Fig. 1, Fig. 4 is a top plan view of the same. Fig. 5 isa plan view of the dial.

1 is the supporting frame. 2 is the driving shaft having bearingstherein.

8 is the driving wheel taking power through a suitable transmitter froma wheel on the countershaft, or other suitable rotary member, of themachine to be operated.

The time indicating function of the device is de endent upon thecondition that the Whee 3 be driven a predetermined number of rotationsper minute. This can be effected by a properly figured transmissionmechanism from the machine to be indicated. The machines to he mostcommonly used as contemplated, are for instance, eX- tractors, whichwhen working at proper efficiency has a uniform speed.

As shown, the worm mechanism is rotated Specification of Letters Patent.

Application led April 20, 1908.

Patented July 13, 1909.

Serial N0; 428,016.

so that when the wheel 3 has one hundred and fifty rotations per minute,the halfhour dial will rotate once every thirty minutes. The dial may heused to indicate the subdivisions of a greater period, say, an hour, byappropriate change in the rate of rotation of w eel 3.

4 is a worm on shaft 2.

5 is a shaft transverse to shaft 2, having bearings in upright pillars6.

7 is a worm wheel on shaft 5 driven by worm 4.

8 is a worm on shaft 5.

9 is a shaft transverse to shaft 5, having a worm wheel 10 driven byWorm 8. Shaft 9 is the final or driven shaft, upon the u per end ofwhich is a dial 11, having a notc 12 and time indications 13, see Fig.5. As shown, the dial is graduated to show five minutes and multiplesthereof up to 30.

14 is an armV pivoted upon shaft 2, in a plane parallel to shaft 9, aspring 15 drawing the arm normally inward so that its upper end bearsagainst the periphery of disk 11.

16 is a rock-collar pivoted on shaft 2.

17 is a bracket on arm 14 upon which is pivoted a Enger 18, extendingopposite to the side of the periphery of worm wheel 7 in position to beengaged and lifted by the pins 19 attached to the outside of theperiphery of Worm wheel 7.

20 is an arm on collar 16 connected by wire 21 to finger 18. 22 is anarm on the other side of collar 16 connected by Wire 23 with the clapper24 of bell 25, the clapper spring 26 exerting strain on rock collar 16tending to pull finger 18 downwardly. Disk 11 has a split sleeve 29engaging frictionally on the end of shaft 9, the friction beingsufficient to rotate the disk with the shaft but allowing the shaft torotate in the sleeve when the l disk is held stationary by finger 18.

In o eration the dial is set for the selected time, the number of theselected. period, say, five minutes being placed adjacent to the arm 14.When the machine is o erated the dial will be slowly rotated throng theWorm mechanism, the arm 14 being held in its outward position by theperiphery of dial 11, the finger 18 is held outside of the line ofmovement of pins 19, at the end of the five minutes the notch 12 willhave arrived opposite to the arm 18 and the arm will be drawn by sfpring15 into the said notch, thus bringing nger 18 opposite the pin 19; aseach pin passes the linger it will lift the finger and release it with asna which operates the bell or signal through tlie connecting mechanismof the rock collar, the bell Will thus continue to ring at regularintervals until the operator responds to the signal and stops themachine or gives theattention required.

This attachment is applicable in connection With any machine Which doesa given Work in a certain time. It is a labor saver, avoiding timelosses, and enabling the foreman to keep accurate tab on each machine inhis de artment. lt is thus insured that the iull e cienoy of eachmachine shall be obtained.

Having described my invention, I claim z- In a device of the classdescribed, a driving and a driven shaft, speed reducing transmissionmechanism connecting them, a notched disk frictionally engaging thedriven shaft to normally rotate therewith, a pivoted spring actuatedlever adapted to engage the periphery of the disk and enter the notch,and signal mechanism adapted to be operated by the rotary mechanismWhile the lever holds the disk against movement by its engagement Withthe slot, substantially -as described.

In testimony whereof, l have hereunto set my hand.
